1 Claim. 1

This invention relates to improvements in flushless toilets of the character employed out side or inside of buildings and has for the primary object the provision of a specially constructed mechanism for opening and closing the door or trap covering the toilet pit that is associated with the toilet proper.

One of the objects of the present invention is the provision of a means adapted to be operated by the feet of the user of the toilet for automatically opening and closing the door covering the toilet pit.

Another object of the present invention is the provision of a combined lever and gearing mechanism for automatically controlling the door covering the pit.

A further object of the present invention is to provide an improved vent associated with the pit and door outlet for venting the pit. A still further object of the present invention is the provision of elongated upwardly extending ilue in communication with the pit for venting the same to provide a suction ian in the ilue for automatically drawing the fumes from thc pit.

A still further object of the present invention is the provision oi an outside lushless toilet that is sanitary, simple in construction, economical to manufacture and highly eilicient and serviceable 1n use.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of the speciiication, wherein for the purpose of illustration like numerals designate like parts throughout the same,

Fig. l is a top plan view of the improved toilet,

Fig. 2 is a central vertical sectional view of the same,

Fig. 3 is a side elevational view of the toilet,

Fig. 4 is a vertical sectional view taken on line 4-4 of Fig. 3 looking in the direction of the arrows, and

Fig. 5 is an end elevational view of the device, for the purpose of clarity the foot lever and foot gear being removed.

Referring in detail to the drawings and the numerals thereof, wherein for the purpose of illustration like numerals designate like parts throughout the same, the numeral 'i designates the toilet bowl as a whole and the numeral 8 the seat thereof, which seat is apertured as at 9 for the passage therethrough of human excretion. An outlet EG leads downwardly from the bowl to a conventional pit, not shown, and a downwardly extending urine receiving trough Il leads to and within the front portion of the bowl as disclosed to advantage in Fig. 2. A horizontal door I2 is positioned beneath the trough Il and covers the said outlet and is pivotally secured to the body of the outlet as at I3. The numeral I4 designates a suitable stop for retaining the door in a horizontal position as disclosed to advantage in Fig. 2.

A gear member l5 is forme-d on the outer extremity of the door l2 and engages an idler gear l5, which idler gear is engaged by the drive gear ll. A substantially horizontal shaft i8 is iixed to the said drive gear Il, which shaft I3 is xed to a foot lever I9 of substantial width.

It is obvious, when a user of the toilet stands or otherwise exerts a downward pressure on the said foot lever I9, the gearing mechanism associated therewith will cause the swinging door l2 to automatically open as shown in dot and dash lines in Fig. whereby the bottom outlet i6 will be open for receiving urine from the user of the chute Il. pressed downwardly the swinging door l2 will automatically open. A conventicnal upwardly extending vent 29 projects from the Tear portion of the toilet bowl l and communicates therewith through the vent opening 2i, whereby all odors from the bowl and toilet outlet are conveyed therefrom. A conventional electrically operated suction fan or blower 22 is associated with said vent to assist in quickly carrying ofi the odors. A suitable electric conductor 23 controlled by an electric switch 2d and operated by the foot lever E9 is provided for controlling the operation of the blower. Thus when foot pressure is exerted on the lever I9 to raise the door i2, the blower is automatically operated for venting the toilet bowl l. The blower can be a windmill, if desired.

It is to be understood that the form of my invention herewith shown and described 'is to be taken as a preferred example of the same and that various changes relative to the shape, size, material and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described our invention, we claim:

A toilet structure comprising a housing, an apertured seat on the upper portion thereof, an inclined trough extending in front of and beneath the seat and leading to and within the housing, said housing having a downwardly extending passageway, a hingedly secured cover closing said passageway, means including a gearing mechanism for opening said cover, said means including a foot lever, and a mechanism including a plurality of gears associated with the foot lever and door.
